DOOR-FASTENER.

\ Application filed July 13, 1909. Serial No. 507,334.

To all whom it may concern: R Be it known that I, NATHAN VVILLIAMES R1311); a citizen of the United States, residing at' Roundaway, in the county of Coahoma and State of Mississippi, have invented certaiiitnew and useful Improvements in Door- Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains topmake and use the same.

My invention relates to new and useful improvements in door fasteners and my object is to provide means for securely holding a door in its closed position and a further object is to provide means for increasing the thickness of the fastening device to ac commodat e the same to doors varying in listanres from the face of the door lamb.

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claim.

In the accompanying drawings forming part of this application, Figure l is a perspective View of the door fastener, and, Fig. 2 is a plan view of the fastener applied to use, the door and jamb being shown in sections.

Referring to the drawings in which similar reference numerals desi nate corresnonding parts throughout the several views, 1, 2 and 3 indicate the plates of my improved door fastener, which are preferably constructed of fiat sections of metal, one end of each of the blades being bent at' right angles to form anchors l, 5 and 6, respectively, the

opposite ends of said blades being pi\-'otally secured together in any preferred manner, as by means of a bolt T, the blade 2 being slightly greater in length than the blade 1 and the blade'fi slightly greater in length than the blade 2, whereby said blades may be swung one above the other.

The anchors 4, 5 and ti,v are provided with teeth 8, 9 and 10, respectively, which teeth are adapted to engage the face of the door jamb 11 when the door 12 is closed, the

action of closing the door, forcing'the anchors on the plates into the ambt.

The fastening device is provided with a locking plate 13, which is pivotally mounted on the bolt 7 and is 1 rovided at this point with an elongated slot 13 to permit lonrlr gitndlnal ad3ustmcnt ot the plate, one end of the locking plate having an angular extension 14, which is adapted to extend over the face of the door when the lock is notches in the plates and in view of the elongated slot in the locking plate, the an gular extension may be seated in any of the notches in the plates to bring the extension adjacent the face of the door, thus accommodating the fastener for doors of varying thicknesses. i

In applying the fastener to use, any ine of the to the other blades and theanchor thereon engaged with the door jamb and said door then closed, which will result in forcing the anchor inwardly and firmly seating the same in the jamb.

The plate 13 is then swung on its pivot and the notch therein engaged with one'of the notches in the blade engaged with the jauib, this operation bringing the angular extension into engagement with the inner face of the door, thereby securely holding the door against being forced or otherwise opened until such time as the locking plate 'is swung out. of engagement with the notches in the plate.

Should the edge of the door extend a distance from the face of the jainb as shown by dotted lines in Fig. 2, all of the blades may be brought into alinement with each other and placed in engagement with the jainb, thus filling the space between the edge of the door and jainb.

The locking plate 13 is of sulficient length as to have its free end extend a distance beyond the bolt 7, thus forming a handle, whereby the blade may be readily grasped and swung on its pivot to engage 0r disengage the same from the blades and when the device is not in use, the parts thereof may be folded together so as to occupy but a minimum amount of space.

\Vhat I claim is:

A fastening device comprising aplurality of blades pivotally attached adjacent one blades may be swung at right angles,

A 1 ML l of then ends and havmg anchors 2n then: In testnnony whereof I have slgned my ()PPOHI'IG ends, smd blades hnvlng reglstenng name to thls speclficatlon 1n the imesence of notches l'herem, a locklng plate hnvlng a two HllbSCl'lblllg \vltnesses.

slot therein to engage the pivoting means NATHAN WILLIAMES REID and an angular extension at one end of XVitnesses:
